TECHNICAL FIELD

The exemplary embodiments disclosed herein relate to paging controlsystems and/or methods that help users navigate through large or smalldatasets and, more particularly, the exemplary embodiments disclosedherein relate to paging systems and methods that help users navigatethrough large or small datasets by providing paging control elementsaccording to either a binary subdivision approach or a serialprogressive approach. Paging control elements are displayed according toeither the binary subdivision approach or the serial progressiveapproach in dependence on a determination as to which approach is moreadvantageous based at least in part on factors such as, for example,total number of pages, current page location, distance to end points,screen size, etc.

BACKGROUND AND SUMMARY

Many known paging control systems and methods are suitable for datasetswith a small number of elements. One basic example involves providing“next” and “back” navigation elements. This basic example has beenimproved upon by adding “jump to end” and “jump to beginning” navigationelements. Another known variation involves initially displaying a shortlist of sequentially ordered numbers corresponding to pages adjacent toa currently selected page. Oftentimes, the selected page is highlightedor otherwise emphasized. Frequently, only a small number of pages areshown at a time. For example, sometimes only 3, 5, or 10 elements areshown. When a user is “in the middle” of a large number of pages, thepresence of ellipses (i.e., “ . . . ”) may indicate the existence ofpages on either side of the currently selected page. For example, whenthere are 10 total pages, the currently selected page is 1, and up to 2navigation elements are shown on either side of the currently selectedpage, the following paging control elements may be displayed:

-   -   1, 2, 3, . . .        Following the same example, when the user navigates to page 5        (i.e., making the currently selected page 5), the following        paging control elements may be displayed:    -   . . . 3, 4, 5, 6, 7 . . .        As indicated above, “jump to end” and “jump to beginning”        navigation elements may be added to these displays, as        appropriate. That is, in the former example, a “jump to end”        navigation element would be appropriate, whereas a “jump to        beginning” navigation element would not be appropriate because        the user is already at the first page. In the latter example,        both “jump to end” and “jump to beginning” navigation elements        may be displayed, since the user is in the “middle” of the        pages.

As can be seen from the above, there are a number of paging controltechniques than can be successfully implemented, particularly withrespect to small datasets. Unfortunately, there also is a need toefficiently and effectively visualize and navigate among more and moreelements. This need may be becoming increasingly important as more andmore options are presented to users, more data becomes available forresearch and/or searching, etc. Indeed, this need has manifested itselfin many areas of computer-related technologies. For example, researchersmay need to navigate among large and complex datasets, online shoppersmay need to navigate among a potentially large number of products ofinterests, searchers may need to traverse large numbers of web pages orother search results when looking for an item of interest, etc.Currently, there is a lack of display techniques oriented towardsvisualizing and navigating among large datasets, thus making itdifficult for users to process them.

Moreover, although the techniques described above are suitable for smalldatasets, they often are cumbersome or even unmanageable in connectionwith large datasets. For example, it is easy to see how the abovedescribed example paging elements would be extremely difficult to use inconnection with datasets of over as few as 50, 100, or even 1,000 totalelements. However, it will be appreciated that many searches may returna number of results well over these example amounts. Indeed, anelectronic product registration system that manages several millionentries cannot be suitably navigated using these conventional controls.

To complicate matters, the need to navigate among large numbers ofelements often is tempered by the need to simultaneously provide forvisualization and/or navigation among small numbers elements. In otherwords, not every dataset a researcher is interested in will havemillions of records, would-be consumers might find only a small numberof products that meet their criteria, search results may be few ratherthan many, etc. Consequently, it is difficult to create a product thatis flexible enough to accommodate both small and large datasets, as (1)small dataset paging control techniques are not well-suited for largedataset paging control techniques, and (2) there currently is a dearthof large dataset paging control techniques available. Even if there werelarge dataset paging control techniques that could be applied to smalldatasets, it is likely that they would suffer from a problem similar tothat described above in that they would not work well for such sets.

Thus, it will be appreciated that it would be advantageous to provideflexible paging control systems and methods. In other words, it would beadvantageous to provide flexible paging control systems and methods thatare capable of aiding in user visualization and navigation amongdatasets of large and small numbers of elements.

One aspect of certain exemplary embodiments relates to paging systemsand methods that help users navigate through large or small datasets byproviding paging control elements.

Another aspect of certain exemplary embodiments relates to pagingsystems and methods that provide paging control elements according toeither a binary subdivision approach or a serial progressive approach.

Still another aspect of certain exemplary embodiments relates todisplaying paging control elements according to either the binarysubdivision approach or the serial progressive approach in dependence ona determination as to which approach is more advantageous based at leastin part on factors such as, for example, total number of pages, currentpage location, distance to end points, screen size, etc.

In certain exemplary embodiments, a paging control method enabling auser to navigate through a plurality of data elements displayed on adisplay of a computer of the user is provided. A subset of the pluralityof data elements is displayable in each of a plurality of pages, withthe plurality of pages including at least a first page and a last page.Paging control elements are designated for the first and last pages.Information identifying a currently selected page is received. When thecurrently selected page is either the first page or the last page: it isdetermined whether additional paging control elements are to bedisplayed according to either a serial progressive approach or a binarysubdivision approach, and additional paging control elements aredesignated for display between the paging control elements for the firstand last pages in accordance with the approach selected in thedetermining. When the currently selected page is between the first andlast pages: it is determined for a first sub-range corresponding to arange between the first page and the currently selected page, whetheradditional paging control elements are to be displayed according toeither a serial progressive approach or a binary subdivision approach;it is determined for a second sub-range corresponding to a range betweenthe currently selected page and the last page, whether additional pagingcontrol elements are to be displayed according to either a serialprogressive approach or a binary subdivision approach; and additionalpaging control elements are designated for display between the pagingcontrol elements for the first and last pages in accordance with theapproaches selected for the first and second sub-ranges in thedetermining. The currently selected page is formatted for display on thedisplay of the user such that it includes all designated paging controlelements.

In certain exemplary embodiments, a computer-readable storage mediumcomprising a paging control program for enabling a user to navigatethrough a plurality of data elements may be provided, wherein theprogram, when executed by the computer performs instructionscorresponding to this and/or other methods.

Similarly, in certain exemplary embodiments, a corresponding datavisualization system may be provided, with the system comprising acomputer having a display and paging control programmed logic circuitrycapable of acting similar to the above-described and/or other methods.In such exemplary embodiments, for example, the paging controlprogrammed logic circuitry may be further configured to re-format thecurrently selected page upon a user selecting a new page to be thecurrently selected page.

DETAILED DESCRIPTION

Certain exemplary embodiments relate to paging control systems andmethods that continuously or substantially continuously regenerate thecontrol user interface at each user-interactive step towards a targetpage by re-determining the mid-point interactive elements using binarysubdivision and then switching to serial progressive mid-point elementswhen the distance between the current step and the appropriate endpointof the dataset determines the binary subdivision approach to be lessadvantageous than the serial progressive approach. More particularly,certain exemplary embodiments relate to a technique that includes apaging control that at each progressive interaction step towards atarget page dynamically generates updated user interface elements so asto provide for rapid navigation to a target page—regardless of howextensive or small the range of pages in the dataset. The controlimplementation of certain exemplary embodiments reduces the number ofuser interface elements dynamically based on the range, thus reducingthe number of interaction elements when they are expected to providelittle or no additional value to the user.

A paging control technique according to certain exemplary embodimentsprovides an improved approach for providing interactive mid-point userinterface page navigation elements. The control implementation uses apage target approach model that leverages two alternative approaches todynamically creating user interface elements. The result is a controlthat provides a space-wise efficient intuitive user interface fornavigating through both large and small datasets. The technique used todetermine which and how many interactive elements to display makes useof multiple input criteria to determine what user interface elements toprovide to the user for any given dataset size and the currently viewedposition within that dataset. That is, for any given current positionwithin the dataset, the paging control technique of certain exemplaryembodiments splits the dataset into two ranges: beginning to currentpage, and current page to end. Up to a predetermined number ofiterations of binary subdivision (e.g., 5, 6, 7, etc. iterations) arethen used to calculate what mid-point user interaction elements torender for the user between the current position and either endpoint.When the binary split approach is determined to be the best approach forany given range; to keep the interaction elements to an efficient number(e.g., based on the rendering area provided), only the inner mid-pointsbetween the current page and the particular endpoint are rendered. Whenthe serial progression approach is used, all intermediate mid-points(pages) between the current position and the endpoint are rendered asinteraction elements.

FIGS. 1-10 demonstrate how the paging control techniques of certainexemplary embodiments are implemented. It will be appreciated that zeroor negative values for Total Items and Items/Page in the examples arenot valid or of value in demonstrating the techniques of certainexemplary embodiments/paging control. In this regard, FIG. 1 is a pagingcontrol in an illustrative example where there are 100 total items, 10items displayed per page, and the current page is page 1, in accordancewith an exemplary embodiment. Given these parameters, there are 10possible pages on which elements can be displayed. The distances fromthe current page to each of the extremes (the beginning and end pages)are determined. In this example, the current page is the beginning pageand there are 8 pages between the currently selected page and the lastpage.

It is then determined that the serial approach is best suited for thisdisplay environment. As explained in greater detail below, thisdetermination can be based on any number of different criteria. Incertain exemplary embodiments, the criteria may be as simple asdetermining whether the total number of pages is less than apredetermined threshold, which may be related to the size of the displayarea. For example, the display area may be capable of accommodating 5,10, 12, 15, 25, 27, 30, or some other number of paging control elements.If the number of pages is less than this number, then the serialapproach may be used. In this example, because the display area is largeenough to accommodate page elements for at least 10 different pages, theserial approach can be used for displaying paging control elements fromthe currently selected page to the end point. It will be appreciatedthat no determination need be made for the range between the currentlyselected page and the beginning page, since the currently selected pagein this example is the beginning page. In other words, some checking maybe performed to determine whether the current page is either thebeginning page or the ending page. If either condition is met, thedisplay approach for that range need not be determined.

In this example, ten different paging control elements are provided.Associated with each paging control element is a page label.Furthermore, the currently selected page is indicated in the white box.Optionally, in certain exemplary embodiments, the number within thewhite box may be editable so that a user can jump directly to a page ofinterest, e.g., by entering a page number and initiating the jump (forexample, by pressing the enter key on a keyboard, clicking a particularbutton, etc.) without selecting a separate paging control element.

Although not explicitly shown in FIG. 1, it will be appreciated that theitems or elements of interest within the page range may be displayed inthe display portion. The element or item numbers may be indicated in anoptional display area, along with the total number of elements. Thus, inthe FIG. 1 example, because page 1 is selected, there are 10 totalpages, and 100 total items, the optional display area indicates thatitems 1-10 of 100 are displayed.

FIG. 2 is a paging control that includes the illustrative exampleconditions of FIG. 1, except that the current page is page 5, inaccordance with an exemplary embodiment. The current page may be set topage 5 by the user selecting the fifth paging element below the pageindicator with the label “5.” Alternatively, the current page may be setto page 5 after the user designates that the fifth page should be jumpedto by inserting the number “5” in the editable current page box in FIG.1 and pressing an appropriate key. In any event, the current page is nowin the middle of the extremes, and paging control elements are providedfor pages 1-4 to the left of the current page indicator while pagingcontrol elements are provided for pages 6-10 to the right of the currentpage indicator.

Thus, in certain exemplary embodiments, it is determined for the rangebetween the first page and the current page and the range between thecurrent page and the last page which display approach should be used. Inthe FIG. 2 example, the serial progressive display approaches are usedfor both ranges. The determination that the serial progressive displayapproach should be used for both ranges may be based on the fact thatthe total number of pages is less than a threshold limit, as describedabove. Alternatively, the determination that the serial progressivedisplay approach should be used for both ranges may be based on the factthat the individual ranges are less than respective thresholds. In stillanother possibility, the determination that the serial progressivedisplay approach should be used for both ranges may be based on the factthat a predetermined number of sub-divisions (e.g., at least 5sub-divisions) cannot be performed for either of the ranges. Othercriteria may be used in place of or in combination with any or all ofthese potential tests in certain exemplary embodiments.

Similar to the above, the element or item numbers may be indicated in anoptional display area, along with the total number of elements. Thus, inthe FIG. 2 example, because page 5 is selected, there are 10 totalpages, and 100 total items, the optional display area indicates thatitems 41-50 of 100 are displayed.

FIG. 3 is a paging control that includes the illustrative exampleconditions of FIG. 1, except that the current page is page 10, inaccordance with an exemplary embodiment. In some respects, FIG. 3 is the“mirror image” of FIG. 1. That is, the currently selected page is thelast page (page 10) in the FIG. 3 example, instead of the first page(page 1) in the FIG. 1 example. Just as the serial progressive approachis determined to be the better approach for the display of thenavigation elements in FIG. 1, the serial progressive approach also isdetermined to be the better approach for the display of the navigationelements in FIG. 3.

In view of the above, it will be appreciated that the illustrativeconditions that lead to the FIGS. 1-3 examples only used the serialprogressive approach. However, when there is a greater amount of data tobe displayed and/or a greater number of pages that are displayable, theserial progressive approach may not be appropriate for efficiently andeffectively navigating through and/or visualizing the same. In thisregard, a further example is presented in connection with FIGS. 4-9 thatinvolve a greater number of elements and pages compared to the examplepresented in connection with FIGS. 1-3. As will become clearer from thedetailed description below, the example is presented in connection withFIGS. 4-9 involves scenarios in which both the serial progressiveapproach and the binary subdivision approach to displaying pagingcontrol elements are implemented.

FIG. 4 is a paging control in an illustrative example where there are1000 total items, 10 items displayed per page, and the current page ispage 1, in accordance with an exemplary embodiment. Because the currentpage is page 1, elements 1-10 of 1000 would be displayed. Given theseexample parameters, it will be appreciated that the items will bedisplayed throughout 100 different pages. Thus, if the serialprogressive approach were to be used, 100 different paging controlelements would be needed. However, it would be appreciated thatdisplaying 100 different paging control elements would be difficult touse, and might not be feasible, given the amount of “real estate”available on the display device. Thus, according to the FIG. 4 example,when the current page is 1, it is determined that the better approach todisplaying paging control elements involves the binary subdivisionapproach.

Because the first page is the currently selected page, the displayelements for only one range (from beginning to end) needs to bedisplayed. In certain exemplary embodiments, when the binary subdivisionapproach is implemented, the “next” and “last” elements may beautomatically displayed. In this example, the “next” element would be anelement for navigating to page 2. The last element in the range would bean element for navigating to page 100. This sub-range may be divided todetermine the first intermediate point to display. In this example,adding the lowest element (2) and the intermediate endpoint element(100) and dividing by 2 results in the first intermediate point to bedisplayed (51).

To determine the next intermediate point to be displayed, theintermediate endpoint element now may be reset so as to correspond tothe first intermediate point (51), and the process may be repeated. Inother words, adding the lowest element (2) and the new intermediateendpoint element (51) and dividing by 2 results in the secondintermediate point to be displayed. In this example, the result of thecalculation, i.e., 26.5, is not a whole number. To arrive at a wholenumber, a rule for handling non-whole number calculations may beimplemented. In certain exemplary embodiments, truncation may be usedwhich in this illustrative example would make the second intermediatepoint equal to 26. In certain other exemplary embodiments, rounding upor down may be used. Rounding up in this illustrative example would makethe second intermediate point equal to 27. The rule for handlingnon-whole number calculations may be implemented consistently whenever anon-whole number is encountered in certain exemplary embodiments.Alternatively, in certain exemplary embodiments, various rounding rulesmay be used depending other factors such as, for example, how close theintermediate element would be compared to the next adjacent intermediateelement, whether the sub-range is to the left or right of the currentlyselected page, etc. For example, rounding down may be used when thesub-range is to the right of the currently selected page, whereasrounding up may be used when the sub-range is to the left of thecurrently selected page—or vice versa. In any event, in the FIG. 4example, the non-whole number is truncated so that the secondintermediate point is equal to 26 and a corresponding paging controlelement is displayed therefor.

This process may be repeated such that other paging control elements arecalculated. In the FIG. 4 example, intermediate further paging controlelements are provided for pages 14 ((26+2)/2), 8 ((14+2)/2), 5((8+2)/2), and 3 (the truncated result of (5+2)/2). The paging controlelement for page 3 may stop the process, since it is directly adjacentto the lowest added element (2). In other words, in certain exemplaryembodiments, the binary subdivision approach may be used to repeatedlydetermine intermediate paging control elements until a paging controlelement that is directly adjacent to the lowest added element is found,thereby indicating that there are no additional whole numbers betweenthe two. In certain exemplary embodiments, the same and/or differentevents may trigger the end of the binary subdivision. For example, incertain exemplary embodiments, a maximum number of binary subdivisionsmay be set, and additional binary subdivisions (e.g., 5, 6, 7, 10, etc.)may not be performed beyond this threshold. This threshold may bepredetermined, for example, based on screen size, or other factors.

FIG. 5 is a paging control that includes the illustrative exampleconditions of FIG. 4, except that the current page is page 51, inaccordance with an exemplary embodiment. Because the current page ispage 51, elements 501-510 of 1000 would be displayed. Additionally,because the current page is page 51 and thus is between the extremefirst point (page 1) and end point (page 100), paging control elementsmay be provided for the ranges the left and right of the current pageelement (51). As above, if the serial progressive approach were to beused, 100 different paging control elements would be needed, with 50being provided to the left of the currently selected page element and 49being provided to the right of the currently selected page element.Thus, it is determined that the binary subdivision approach would bebetter suited for both the left and right sub-ranges. A description ofhow the paging elements for these sub-ranges are displayed follows.

First, with respect to the sub-range to the right of the currentlyselected page element, the “next” element would be an element fornavigating to page 52. The last element in the range would be an elementfor navigating to page 100. Similar to the description above,intermediate points may be calculated. In the FIG. 5 example, theintermediate paging control elements include 76 ((100+52)/2), 64((76+52)/2), 58 ((64+52)/2), 55 ((58+52)/2), and 53 (the truncatedresult of (55+52)/2). Because the number 53 is directly adjacent to 52,the binary subdivision stops.

Second, with respect to the sub-range to the left of the currentlyselected page element, the “previous” (as opposed to the “next”) elementwould be an element for navigating to page 50. Similar to thedescription above, intermediate points may be calculated. The firstintermediate paging control element will equal the difference betweenthe “previous” element (50) and the first element (1), divided by 2.Because 24.5 is not a whole number, a nearest whole number may be usedinstead. In the FIG. 5 example, the number is rounded up so that it iscloser to the currently selected page. Accordingly, in this example, thefirst intermediate point thus is 25.

To determine the next intermediate point to be displayed, theintermediate endpoint element now may be reset so as to correspond tothe first intermediate point (25), and the process may be repeated. Inother words, adding the previous element (50) and the new intermediateendpoint element (25) and then dividing by 2 results in the secondintermediate point to be displayed. Again, because 37.5 is not a wholenumber, it may be rounded up, thus resulting in the second intermediateof 38. This process is repeated so that further intermediate points arecalculated. In the FIG. 5 example, these intermediate points include 44((38+50)/2), 47 ((44+50)/2), and 49 (the rounded-up result of(47+50)/2). Because the number 49 is directly adjacent to 50, the binarysubdivision stops.

FIG. 6 is a paging control that includes the illustrative exampleconditions of FIG. 4, except that the current page is page 25, inaccordance with an exemplary embodiment. In other words, the FIG. 6example may be displayed when a user “jumps” to the twenty-fifth page byselecting the appropriate link in the FIG. 5 example. Because page 25 isdisplayed in FIG. 6, items 241-250 of 1000 would be displayed.

In the FIG. 6 example, it is determined that both the left and rightsub-ranges would be better suited to the binary subdivision approach.Accordingly, in addition to displaying the currently selected page (25)along with the first (1), last (100), “next” (26), and “previous” (24)paging control elements, the binary subdivision approach is used todisplay the other paging control elements in the two sub-ranges. In theright sub-range, elements 63 ((26+100)/2), 44 (the truncated result of(26+63)/2), 35 ((26+44)/2), 30 (the truncated result of (26+35)/2), and28 ((26+30)/2) are displayed. In the left sub-range, elements 12 (therounded-up result of (24+1)/2), 18 ((24+12)/2), 21 ((24+18)/2), and 23(the rounded-up result of (24+21)/2) are displayed.

FIG. 7 is a paging control that includes the illustrative exampleconditions of FIG. 4, except that the current page is page 12, inaccordance with an exemplary embodiment. In other words, the FIG. 7example may be displayed when a user “jumps” to the twelfth page byselecting the appropriate link in the FIG. 6 example. Because page 12 isdisplayed in FIG. 7, items 111-120 of 1000 would be displayed.

Unlike the examples in FIGS. 4-6, it is determined that the leftsub-range should be displayed according to the serial progressiveapproach, while the right sub-range should be displayed according to thebinary subdivision approach. This may be determined, for example, bynoting that the currently selected page is within a predefined distanceof either the start point or end point. In certain exemplaryembodiments, one or more points may be setup such that when a usernavigates to or past such a point, the display approach is changed,e.g., from the binary subdivision approach to the serial progressiveapproach, or vice versa. In certain exemplary embodiments, the pointsmay be predefined, e.g., based at least in part on the size of thescreen (e.g., such that no more than 10, 11, 12, 13, etc., pagingcontrol elements can be displayed according to the serial progressiveapproach). In certain exemplary embodiments, the serial progressiveapproach may be used if a predefined number of binary subdivisionscannot be performed (e.g., the serial progressive approach may be usedif 3, 4, 5, etc., subdivisions cannot be made for a range or sub-rangewithout there being redundant numbers).

In any event, returning to FIG. 7, as indicated above, the serialprogressive approach is determined to be better for the left sub-range.Accordingly, paging control elements from the first page (1) to the“previous” page (11) are provided. In contrast, the binary subdivisionapproach is determined to be better for the right sub-range. Thus,paging control elements are provided for pages 13 (the next page), 15,18, 24, 35, and 57, and 100 (the last page).

As can be seen in the FIG. 7 example, different paging control elementimages may be used in accordance with the approach selected. Forexample, when the serial progressive approach is selected, identicalimages are used, suggesting to the user that the “jumps” are the same.In the FIG. 7 example, the icon for the elements displayed according tothe serial progressive approach is an arrow with a small dot next to it.By contrast, different images may be used for the binary subdivisionapproach, e.g., so as to help signify that bigger “jumps” are beingtaken and also to help signify the scale of such “jumps.” Accordingly,the elements displayed according to the binary subdivision approach areshown as small blocks that get larger as the distance from the currentlyselected page increases. Separate icons for the first and last pages areprovided. Of course, it will be appreciated that these and/or otherimages may be used for the paging control elements in certain exemplaryembodiments. Indeed, certain exemplary embodiments of this inventionneed not use different paging control elements depending upon theselected approach. In a similar regard, the area around the currentlyselected page need not be a “box,” and it may or may not be auser-editable field.

FIG. 8 is similar to FIG. 7, in that FIG. 8 is a paging control thatincludes the illustrative example conditions of FIG. 4, except that thecurrent page is page 13, in accordance with an exemplary embodiment. Inthe FIG. 8 example, the serial progressive approach is still used forthe left sub-range, and the binary subdivision approach is still usedfor the right sub-range. Thus, paging control elements are provided forpages 14 (the next page), 16, 19, 24, 35, 57, and 100 for the rightsub-range.

The inventor of the instant application has determined that it may beadvantageous to display the following maximum number of paging controlelements according to the serial progressive approach in certainexemplary embodiments that are capable of displaying 27 separate pointsacross. The number of elements includes the “current” and either the“last” or “first” paging elements.

Total Number of Pages Max. Number of Elements >192 13  96-192 12 48-9511 25-47 10  <25 10Of course, it will be appreciated that other maximum number of elementsmay be defined for use in different exemplary embodiments of thisinvention, and this is merely one example of how the maximum number ofserial progressive points may be setup in one exemplary embodiment.

FIG. 9 is a paging control that includes the illustrative exampleconditions of FIG. 4, except that the current page is page 100, inaccordance with an exemplary embodiment. Thus, similar to FIG. 3described above, only one range is displayed. However, unlike the FIG. 3example, because the difference between the first page and current page(which is in this case the last page) is great, the binary subdivisionapproach is used to display paging control elements for pages 1, 50, 75,87, 93, 98, and 99.

As alluded to above, the number of binary subdivisions to be performedmay be capped in certain exemplary embodiments. For example, dependingon the size of the dataset, more or fewer binary subdivisions may beadvantageous. For example, even though it would be possible to performat least one further binary subdivision for the right sub-range of FIG.8, only five subdivisions are provided. Of course, this number could bevaried to a greater number (e.g., six) or a lesser number (e.g., 4, 3,2, 1, etc.), depending on the exemplary embodiment.

The inventor of the instant application has determined that thefollowing switch points are advantageous in certain exemplaryembodiments that are capable of displaying 27 separate points across.The number of subdivisions does not include the “next” and either “last”or “first” paging elements.

Total Number of Pages Number of Subdivisions >192 7 97-192 6 49-96 525-48 4  <25 3Of course, it will be appreciated that other switch points may be usedin different exemplary embodiments of this invention, and this is merelyone example of how such switch points may be setup in one exemplaryembodiment.

FIG. 10 is a paging control in an illustrative example where there are10000 total items, 10 items displayed per page, and the current page ispage 1, in accordance with an exemplary embodiment. Thus, it will beappreciated that there are a large number of pages through which a usermight navigate. The binary subdivision approach would be better suitedfor this example. Additionally, because the FIG. 10 example has a largenumber of pages, many binary subdivisions are possible. However, inaccordance with the description provided above, only seven subdivisionsmay be performed such that nine paging elements to the right of thecurrently selected page are provided, e.g., to aid in user navigationand/or visualization of the dataset. Indeed, too many navigation buttonsmay be troublesome for the user, even when the binary subdivisionapproach is used.

Although the foregoing example have included information pertaining tonumber of elements, number of elements to be displayed per page, currentpages, switch points, maximum number of elements to display according tothe serial progressive approach, maximum number of elements to bedisplayed on a page, etc., it will be appreciated that these parametershave been provided by way of example and without limitation. Otherparameters may be predefined for a user in certain exemplaryembodiments. Alternatively, some or all of the foregoing and/or otherelements may be user-definable in certain exemplary embodiments.

FIG. 11 is a flowchart illustrating an illustrative process fordisplaying paging control elements in accordance with an exemplaryembodiment. In other words, FIG. 11 is an example paging control methodenabling a user to navigate through a plurality of data elementsdisplayed on a display of a computer of the user. A subset of theplurality of data elements may be displayable in each of a plurality ofpages, and the plurality of pages may include at least a first page anda last page. Paging control elements for the first and last pages aredesignated in step S1. Information identifying a currently selected pageis received in step S3.

In step S5, when the currently selected page is either the first page orthe last page, it is determined whether additional paging controlelements are to be displayed according to either a serial progressiveapproach or a binary subdivision approach. Additional paging controlelements also are designated for display between the paging controlelements for the first and last pages in accordance with the approachselected in the determining.

Similarly, in step S7, when the currently selected page is between thefirst and last pages, it is determined for a first sub-rangecorresponding to a range between the first page and the currentlyselected page whether additional paging control elements are to bedisplayed according to either a serial progressive approach or a binarysubdivision approach, and it is determined for a second sub-rangecorresponding to a range between the currently selected page and thelast page whether additional paging control elements are to be displayedaccording to either a serial progressive approach or a binarysubdivision approach. Additional paging control elements also aredesignated for display between the paging control elements for the firstand last pages in accordance with the approaches selected for the firstand second sub-ranges in the determining.

In step S9, the currently selected page is formatted for display on thedisplay of the user such that it includes all designated paging controlelements. As illustrated above, in certain exemplary embodiments, whenthe currently selected page is either the first page or the last page,the determining may depend on a number of pages between the first pageand the last page; and when the currently selected page is between thefirst and last pages, the determining for the first sub-range depends ona number of pages between the first page and the currently selectedpage, and the determining for the second sub-range may depend on anumber of pages between the currently selected page and the last page.

In one or more steps not shown, data may be retrieved and/or displayedin accordance with the currently selected page. Such data may beretrieved, for example, from a storage location located on or remotefrom the user's computer, across a network, a database, etc. Forexample, certain example embodiments may be useful for visualizing datafrom an electronic registration (ER) database that includes productregistration, repair, warranty, policy, and/or other information.

In certain exemplary embodiments, the designating for the serialprogressive approach may comprise designating paging control elementsfor each successive page between start and end pages in a range orsub-range. In certain exemplary embodiments, the designating for thebinary subdivision approach may comprise calculating a midpoint pagebetween the start and end pages; setting the end page to the midpointpage; and repeating this process. For example, the process may berepeated no more than a predetermined number of times. In certainexemplary embodiments, the calculating of a midpoint may furthercomprise rounding to a whole number closest to the currently selectedpage when the calculating of the midpoint does not result in a wholenumber.

According to certain exemplary embodiments, the binary subdivisionapproach may not be selected unless at least three subdivisions arepossible. According to certain exemplary embodiments, the serialprogressive approach may not be selected if greater than a predeterminednumber of (e.g., 13) paging control elements would be designated fordisplay.

According to certain exemplary embodiments, when the currently selectedpage is between the first and last pages, at least one paging elementfor at least one corresponding page directly adjacent the currentlyselected page also may be designated.

Of course, it will be appreciated that any or all of the techniquesdescribed above may be re-performed upon a user selecting a newpage—with the new page being designated as the currently selected page.Although the term “pages” has been used herein, it will be appreciatedthat the instant invention is not limited to “web pages.” For example,any display screen rendered on a computerized display could beconsidered a “page” according to the usage of the term herein.Furthermore, a “page” according to the usage of the term herein may beonly a portion of a larger display. The larger display may or may notchange in certain exemplary embodiments, although at least some area ofthe larger display will be updated (e.g., with new data for thedifferent “page” and/or updated paging control elements) when acurrently displayed or currently selected “page” is changed.

Although certain example embodiments have referred to the binarysubdivision approach (e.g., where the ½, ¼, ⅛, etc., pages aredisplayed), it will be appreciated that other subdivision approachescould be used in place of or in addition to this approach. For example,rather than using midpoint, one-third points, one-quarter points, etc.,could be used in connection with certain example embodiments.

The features, aspects, advantages, and exemplary embodiments describedherein may be combined in various combinations and sub-combinations torealize yet further embodiments of this invention.
